This invention relates to masonry and more particularly to a building block formed of concrete or any other desired substance which may be molded.

One object of the invention is to provide a building block having spaced sections connected and firmly retained in proper spaced relation to each other so that, u men a wall is built by laying blocks in tiers one upon another, spaces will be formed in the wall and thereby prevent moisture from seeping through a wall.

Another object of the invention is to so form the sections constituting a single block with spaces between the sections will extend diagonally of the block and be so disposed with respect to the block that, when a Wall is built with the blocks of one tier disposed in staggered relation to the blocks of an adjoining tier, the spaces of the blocks will be disposed out of registry and thereby eliminate the formation of passages extending entirely through a wall and materially increase th strength of the wall.

Another object of the invention is to so form the building block that, when, a wall is built, it will have the appearance of a solid wall when viewed from either its inner or its outer surface.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of a portion of a wall built of blocks formed in accord ance with this invention,

Fig. 2 is a longitudinal sectional view through one of the blocks,

Fig. 3 is a topplan view of a portion of the wall shown in Fig. 1, and

Fig. 4 is a top plan view of a block used at a corner of a wall.

In order to form a wall, such as shown in Fig. 1 and indicated in general by the numeral 1, blocks formed in accordance with this invention and indicated in general by the numeral 2 are laid in tiers with mortar between the blocks, and it should be noted that the blocks of one tier are disposed in staggered relation to the blocks of an ad joining tier and each block rests upon adjoining end portions of blocks in the tier be- .mold in which the sections are neath it. Each of the blocks is formed as shown clearly in Fig. 2, and referring to this figure it will be seen that the block consists of companion sections 3 and which extend longitudinally ofthe block in transversely spaced relation to each other. Each of the sections is substantially triangular in shape but taper in opposite directions and these sections cooperate to form a block which is rectangular in shape when viewed in top plan and formed with a longitudinally extending slot 5 disposed in a vertical plane but extending diagonally from one corner portion of the block to an opposite corner portion thereof. l Vhen the sections are being molded, rods or equivalent connecting members 6 are set into a mold with their end portions extending into compartments of the formed and, therefore, when the concrete or clay from which the two sections are formed has hardened, the end portions of the rods or connecting members will be embedded in the sections and firmly held therein. Therefore,,the rods will serve as means to connect companion sections of a block and firmly retain them in proper spaced relation to each other. By referring to 3, it will be seen that since the slots 5 extend diagonally across the blocks and the blocks of each tier are disposed in staggered relation to the blocks forming a supporting tier. The slots in the blocks of one tier will be disposed out of registry with the slots of the blocks upon which they rest. This prevents the formation of vertical passages entirely through a wall and adds materially to the strength of a wall but at the same time spaces are formed in a wall which will serve as chambers to receive moisture which seep through the block sections forming the outer surface of the wall and since only a small amount of moisture will enter each chamber, it will evaporate therein and not be liable to pass through the wall and causing a building to be damp.

At a corner of a building blocks such as shown in Fig. 2, cannot be used as the slots would be exposed. Therefore, I have shown in Fig. 4: a block 7 which will be referred to as a corner block. This block includes a companion sections 8 and 9 which taper in opposite directions and are spaced from each other throughout the major portion of the length of the block by a slot 10 corresponding to the slot 5. It should be noted, however, that the slot 10 terminates in spaced relation to one end of the block instead of extending entirely through it and, therefore, at this end of the block the two sections will be integrally joined and form a solid end portion. A rod 11 similar to the rods 6 extends between the spaced portions of the two sections with its ends embedded therein and will serve very eifectively to brace the two sections and not only retain themin proper spaced relationto each other but also'prevent danger of the section which tapers toward the solid end portion of the block being accidentally broken from this solid end portion if carelessly handled.

Having thus described the invention, I claim:

1. A building block comprising companion sections having their inner side faces spaced transversely from each other and extending diagonally of their upper and lower faces from one corner of the block to a diagonally opposite corner, and means connecting the said' sections and maintaining the same in spaced relation to each other.

2. A building block comprising companion sections of triangular formation having their inner side faces spaced transversely from each other to define a space extending diagonally of the block fromone corner thereof to a diagonally opposite corner, and connecting means extending between said sections and embedded therein and serving to maintain the sections in spaced relation to each other. r

3. A building block comprising companion sections of triangular form having end and outer side faces extending at right angles to each other and their inner side faces spaced transversely and extending diagonallyof the block from one corner thereof to a diagonally opposite corner, and pins extending between said sections in spaced relation to each other'with their end portions embedded in the sections, the said pins servin to join the sections and maintain the same in spaced relation to each other.

4. A wall comprising blocks laid in tiers with the blocks of an adjoining tier disposed in staggered relation to each other with their end portions overlapped, each block consisting of companion sections having their adjacent faces extending diagonally of the the block in spaced relation to each other whereby overlapped portions of blocks inadjoining tiers have the spaces between thei sections entirely out of registry.

In testimony whereof I aflix' my signature.
